The hangcheck live selftest contains duplicate declarations of some
functions that already exist in igt_spinner.c, such as the creation and
deconstruction of a spinning batch buffer (spinner) that hangs an engine.
It's undesireable to have such code duplicated, as the requirements for
the spinner may change with hardware updates, necessitating both
execution paths be updated. To avoid this, have the hangcheck live
selftest use the declaration from igt_spinner. This eliminates the need
for the declarations in the selftest itself, as well as the associated
local helper structures, so we can erase those.
